Porting game from FPE 2 to FPE 3.3

Hello, I've been out of the loop for a while now due to work... sheesh, it's probably been two years, but anyways, I'd like to dust off an old project and port it from Farseer Physics 2.1 to 3.3. First, congratulations on your hard work integrating Box2D
into Farseer! I'm aware that the systems are different and it won't just be a Find and Replace job to get it working, but I'm wondering if there is any sort of guide or comparison for those looking to port from one to the other. I searched for a while online
and on the forums and haven't discovered anything. I'm not asking anyone to write a guide for me if it doesn't exist; if that's the case, I should probably just figure it out myself.
